. avoid such accumulation and thereby add to the comfort of the wearer and also prolong the life of the shoe by eliminating saturation. This object is accomplished, generally, by providing inner and outer soles normally spaced apart and provided with means for circulation of air reaching the foot of the wearer.

More specifically, the inner and outer soles are Y spaced by means of-a strip consisting of a material having the properties of sponge rubber. vOutwardly of the strip, the outer sole is turned upward and fastened to the body of the shoe, but in a manner to provide passages establishing communication.. between the atmosphere and the space between the soles. Also, the inner sole is perforated to extend the air channel to the interior of the shoe.

Pressure on the shoe brings the inner sole into contact with the outer sole and thereby expels air through the sponge rubber strip and through the openings to the atmosphere. When the pressure is relieved, the sponge rubber causes the soles to become spacedagain, during which movement, air is drawn from the atmosphere into the space. Such circulation of air, in communication with the foot of the wearer, readily ventilates all parts of the shoe and evaporates the perspiration before it can accumulate on the foot of the wearer or saturate the shoe.

The invertion is fully disclosed by way of example ln the following description and in the accompanying drawing in which:

Figure 1 is a bottom plan view of the inner sole;

Figure 2 is a fragmentary side elevation of the shoe, partly in section;

Figure 3 is a transverse section showing the -Figure 4 is a similar section, with additional parts applied to the inner sole;

Figure 5 is a transverse section ofthe inner sole. showing also the upper applied thereto;

Figure 6 is a transverse section illustrating (Cl. .3s-3) both the inner and outer soles and the upper, and

Figure 7 is an enlarged view of Figure 6. Reference to these Views will now be made by use of like characters which are employed to ,designate corresponding parts throughout.

The outer sole I consists of sheet rubber of proper thickness and is lined on its upper surface with a fabric sheet 2, as shown more clearly in Figures 2, 3, 4 and 7. The lining 2 is somewhat narrower than the sole I and is placed thereon' in a manner to leave a margin at the edge of the latter, as shown in Figures 3 and 4. The parts I and 2 are held together by rubber cement.

Overlapping the lining 2 is laid a peripheral spacing strip 4 consisting preferably of sponge rubber which has been enclosed on three sides in a friction tape 3. The tape may consist, for example, of cotton ribbon saturated in a sticky rubber cement. The purpose of the strip is to form a space between the inner and outer soles, as will presently appear.

The inner sole is illustrated independently of the outer sole in Figure 5. The inner sole consists of a fiber sheet 6 lined on its lower surface with friction tape 'I. These Vparts require no other adhesive than that in the tape 'I and are formed with a series of apertures 8 for ventilation as will presently appear. The upper 9 of the shoe is brought directly beneath the edge of the inner sole in the case of the athletic shoe here illustrated but may be otherwise attached according to the style. of the shoe. While the lining I has some adhesiveness to hold the upper 9, the latter' is further secured by an outer layer I0 of rubber, known in the art as xing'.

The assembled inner sole and upper, as shown in Figure 5, are laid upon the strip 4, as illustrated more vclearly in Figure 7. In the nal assembly operation, the margin of the outer sole I is turned up at II and cemented and vulcanized to the fixing I0. In forming this joint, a string is placed'between'the parts 3, I0 and II, across the edge of the latter, and is removed when the `cement has'dried. As a result, an opening I2 is formed tov constitute passages for the entrance and egress vof circulating air.

Under pressure, as in walking or running, the resilient strip 4 permits the inner sole to engage the outer sole and force air out through the hole I2 leftby the'removed string. When the pressure is relieved, air is drawn into the space between the inner and outer soles through the same course. In this way a circulation of air is established, and this circulation of airventilates the together due to the fact that their sticky property acts only in the vulcanization operation.

Although a specific embodiment of the invention has been illustrated and described, it will be understood that '-vario-us alterations in the de- -f tails of construction may be madel without departing from the scope of the invention, as indicated by the appended claims.

What I claim is:

1. In a shoe having an inner sole and an cuter sole, a spacing strip inserted between said soles at the edges thereof and consisting of resilientv and porous material, said inner sole having apertures therethrough, ,said soles being joined together at their. edges outwardly of said strip and in a manner to leave openings communicating with the atmosphere and with the space between said soles. i

2. In a shoe having an inner sole and an outer sole, a spacing strip inserted between said soles at the edges thereof and consisting of resilient and porous material, said inner sole having apertures therethrough, an upper attached to the edge of. said inner sole by means of fixing, the

edge of said outer sole being turned up and se, cured to said fixing.

3. In a shoe having an inner sole and an outer sole, a spacing strip inserted between said soles at the edges thereof and consisting of resilient and porous material, said inner sole having apertures therethrough, an upper attached to the edge of said inner sole by means of fixing, the edge of said outer sole being turned up and secured to said fixing, the joint between said fixing and said outer sole having openings communicating with the atmosphere and with the space between said soles.

4. In a shoe having an inner sole and an outer sole, a ber lining upon said outer sole and spaced marginally therefrom, adhesive tape joining said inner and outer soles, a strip mounted in said adhesive tape, saidstrip being a spacer between said soles and consisting of resilient and porous material, said inner solehaving apertures therethrough.

5. In a shoe having an inner sole and an outer sole, a fiber lining upon said outer sole and spaced marginally therefrom, and adhesive tape joining said inner and outer soles, a strip mounted in said adhesive tape, said strip being a spacer between vsaid soles and consisting of resilient and porous material, said inner sole having apertures therethrough, said soles being joined together at their edges outwardly of said strip and in a manner to leave openings communicating with the atmosphere and with the space between said soles.
